Process For Refinishing Corian Countertops

These are my notes from the how-to videos, https://www.youtube.com/watch?v=_xiVtgcHOtE (Parts I and II), with some modifications. Refer to the videos for more detailed, and original, instructions.

(1) Manually remove scratches with 120 grit sandpaper.

(2) Start w/ P220 (220) and orbital sander,

• Move sander front to back, overlapping by 50%;
• Move sander side to side, overlapping by 50%;
• Use circular, clockwise motion front to back, overlapping by 50%;
• Use circular, clockwise motion side to side, overlapping by 50%;

Spray surface with water, remove dust with clean, dry rag;

Use a second dry rag to remove remaining dust and water

(3) Repeat process w/ P600 (400)

(4) Buff with Scotch-Brite Gray (for satin finish), round pads w/velcro

• Mist surface with water;
• Keep surface wet without using too much water;
• Move sander front to back, overlapping by 50%;
• Move sander side to side, overlapping by 50%;
• Use circular, clockwise motion front to back, overlapping by 50%;
• Use circular, clockwise motion side to side, overlapping by 50%;

Spray surface with water, remove dust with clean, dry rag;

Use a second dry rag to remove remaining dust and water

(5) Buff again with Scotch-Brite Gray (for satin finish), round pads w/velcro, and Rejuvenate

• Sprinkle a vey small amount of Perfect Finish on surface of counter (or a couple of drops on buff)
• Mist surface with water;
• Spread mix around, add a little water during process, as needed;
• Move sander front to back, overlapping by 50%;
• Move sander side to side, overlapping by 50%;
• Use circular, clockwise motion front to back, overlapping by 50%;
• Use circular, clockwise motion side to side, overlapping by 50%;

Spray surface with water, remove dust with clean, dry rag;

Use a second dry rag to remove remaining dust and water

(6) Polish using variable speed polisher, buffing pads, and Hope's

• Start with white buffing pad;
• Sprinkle a small amount of Hope's on surface of counter (or a couple of drops on buff)
• Mist surface with water;
• Spread mix around (with polisher off)
• Angle polisher to just use part of one side;
• Add a little water during process, as needed;
• Move sander front to back, overlapping by 50%;
• Move sander side to side, overlapping by 50%;
• Use circular, clockwise motion front to back, overlapping by 50%;
• Use circular, clockwise motion side to side, overlapping by 50%;

Spray surface with water, remove dust with clean, dry rag;
Use a second dry rag to remove remaining dust and water

(7) Repeat polishing/Hope's process, using yellow pad

(8) Manually polish with beeswax compound, using circular motion to blend in.
